Study Notes
Determinants of Immune Response in Transplantation
- The type and severity of the immune response in transplantation are determined by the degree of HLA mismatch between the donor and recipient
Role of HLA Proteins in Transplantation
- The major histocompatibility complex (MHC) system encodes for HLA proteins, which are recognized as foreign by the recipient immune system
Types of Grafts
- Autograft: involves grafting from one area to another in the same individual
- Other types of grafts: allograft, xenograft, and isograft
Immune Privileged Sites
- Transplanted organs at immune privileged sites (e.g. the eye, brain, and pregnant uterus) are generally accepted without significant immune reaction due to the local immune suppression mechanisms
Tissue Compatibility in Transplantation
- The compatibility (or incompatibility) of transplanted tissue is determined by the degree of HLA matching between the donor and recipient
- HLA matching is critical for successful transplantation, as it affects the risk of graft rejection and immunological complications
